Where to find garuga on monster hunter freedom unite

Yian Garuga is a Purple Yian with Poisonous tail, and earblasting yells. you'll find them as early as low rank to as late as G rank quest.

they are annoying cos they love to roam around areas.
my suggestion would be, bring psychoserum, have a tracking skill, throw it a paintball at first encounter/sighting or, clear an are with it's wild life and wait for it to come land then throw a paintball as it lands. if all this fails, then you suck as a hunter.
